Abstract
Abstract A plurality of individual contact areas are distributed over a surface of a semiconductor light conversion element such as a light-emitting diode. A layer of transparent electrically conductive material such as tin oxide is deposited over the surface and in contact with the contact areas, and a conductor member is connected to the transparent layer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
63 words
A TRANSPARENT CONTACT CONSTRUCTION FOR A SOLID STATE LIGHT CONVERSION ELEMENT, COMPRISING A PLURALITY OF INDIVIDUAL ELECTRICAL CONTACT AREAS DISTRIBUTED OVER AND ATTACHED TO A SURFACE OF SAID LIGHT CONVERSION ELEMENT, A LAYER OF TRANSPARENT ELECTRICALLY CONDUCTIVE MATERIAL DISPOSED OVER SAID SURFACE AND IN CONTACT WITH SAID CONTACT AREAS, AND A CONDUCTOR MEMBER ELECTRICALLY CONNECTED TO SAID LAYER OF TRANSPARENT ELECTRICALLY CONDUCTIVE MATERIAL.
Claim 2
Dependent Claim
63 words
A TRANSPARENT CONTACT CONSTRUCTION FOR A SOLID STATE LIGHT CONVERSION ELEMENT, COMPRISING A PLURALITY OF INDIVIDUAL ELECTRICAL CONTACT AREAS DISTRIBUTED OVER AND ATTACHED TO A SURFACE OF SAID LIGHT CONVERSION ELEMENT, A LAYER OF TRANSPARENT ELECTRICALLY CONDUCTIVE MATERIAL DISPOSED OVER SAID SURFACE AND IN CONTACT WITH SAID CONTACT AREAS, AND A CONDUCTOR MEMBER ELECTRICALLY CONNECTED TO SAID LAYER OF TRANSPARENT ELECTRICALLY CONDUCTIVE MATERIAL.
Claim 3
Dependent Claim
15 words
A construction as claimed in claim 1 in which said transparent material comprises tin oxide.
Claim 4
Dependent Claim
22 words
A construction as claimed in claim 2 in which said transparent layer covers over and is in contact with said contact areas.
Claim 5
Dependent Claim
22 words
A construction as claimed in claim 1 in which said contact areas are raised from said surface of the light conversion element.
Claim 6
Dependent Claim
22 words
A construction as claimed in claim 4 in which said transparent layer covers over and is in contact with said contact areas.
Claim 7
Dependent Claim
19 words
A construction as claimed in claim 1 in which said conductor member is partially embedded in said transparent layer.
Claim 8
Dependent Claim
40 words
A construction as claimed in claim 1 in which a second plurality of individual contact areas are distributed over and attached to the opposite surface of said element, and means making electrical contact to said second plurality of contact areas.
